Welcome to BIO101: Introduction to Molecular and Cellular Biology
Specific information about this course and its requirements can be found below. For more general information about taking Saylor Academy courses, including information about Community and Academic Codes of Conduct, please read the Student Handbook.
Explore the basics of molecular biology, including proteins, carbohydrates, lipids, and nucleic acids, water, and other compounds that make up the cell, with an emphasis on the cell membrane, mitosis and meiosis, genetics and gene expression, transcription and translation, and cellular metabolism.
This course is intended for the student interested in understanding and appreciating common biological topics in the study of the smallest units within biology: molecules and cells. Molecular and cellular biology is a dynamic field. There are thousands of opportunities within the medical, pharmaceutical, agricultural, and industrial fields (just to name a few) for a person with a concentrated knowledge of molecular and cellular processes. This course will give you a general introduction to these topics. In addition to preparing for a diversity of career paths, an understanding of molecular and cell biology will help you make sound decisions in your everyday life that can positively impact your diet and health.
This course includes the following units:
- Unit 1: Introduction to Biology
- Unit 2: Basic Chemistry
- Unit 3: Biological Molecules
- Unit 4: Cells and Cell Membranes
- Unit 5: Enzymes, Metabolism, Cellular Respiration
- Unit 6: Photosynthesis
- Unit 7: Cellular Reproduction: Mitosis
- Unit 8: Cellular Reproduction: Meiosis
- Unit 9: Mendelian Genetics and Chromosomes
- Unit 10: Gene Expression
Course Learning Outcomes
Upon successful completion of this course, you will be able to:
- explain basic biological concepts and characterize biological properties common to all organisms;
- apply and evaluate application of the scientific method;
- describe the basic physical and chemical principles that are relevant to biology;
- describe the structure and function of biological macromolecules that are the building blocks of the cell;
- describe the structure and function of cellular components;
- explain how matter and energy are stored and transformed by living systems;
- describe the anabolic and catabolic biochemical pathways and their role in sustaining life in the biosphere;
- differentiate between the different ways organisms reproduce their cells;
- apply general genetic principles in solving problems concerning mendelian and molecular genetics;
- explain how information is stored, copied, transferred, and expressed in biological systems;
- identify significant contributions of science to society through scientific research; and
- transfer and apply your biological knowledge to solve problems in different settings.
Throughout this course, you will also see learning outcomes in each unit. You can use those learning outcomes to help organize your studies and gauge your progress.
The primary learning materials for this course are articles, lectures, and videos.
All course materials are free to access and can be found in each unit of the course. Pay close attention to the notes that accompany these course materials, as they will tell you what to focus on in each resource, and will help you to understand how the learning materials fit into the course as a whole. You can also see a list of all the learning materials in this course by clicking on Resources in the navigation bar.
Evaluation and Minimum Passing Score
Only the final exam is considered when awarding you a grade for this course. In order to pass this course, you will need to earn a 70% or higher on the final exam. Your score on the exam will be calculated as soon as you complete it. If you do not pass the exam on your first try, you may take it again as many times as you want, with a 7-day waiting period between each attempt. Once you have successfully passed the final exam you will be awarded a free Course Completion Certificate.
There are also 5 problem sets in this course. These are designed to help you study, and do not factor into your final course grade. You can take these as many times as you want until you understand the concepts and material covered. You can see all of these assessments by clicking on Quizzes in the course's navigation bar.
Earning College Credit
This course is eligible for college credit via Saylor Academy's Direct Credit Program. If you want to earn college credit, you must take and pass the Direct Credit final exam. That exam will be password protected and requires a proctor. If you pass the Direct Credit exam, you will receive a Proctor Verified Course Certificate and be eligible to earn an official transcript. For more information about applying for college credit, review the guide to college credit opportunities. Be sure to check the section on proctoring for details like fees and technical requirements.
There is a 14-day waiting period between attempts of the Direct Credit final exam. There is no waiting period between attempts for the not-for-credit exam and the Direct Credit exam. You may only attempt each Direct Credit final exam a maximum of 3 times. Be sure to study in between each attempt!
Tips for Success
BIO101: Introduction to Molecular and Cellular Biology is a self-paced course, which means that you can decide when you will start and when you will complete the course. There is no instructor or an assigned schedule to follow. We estimate that the "average" student will take 35 hours to complete this course. We recommend that you work through the course at a pace that is comfortable for you and allows you to make regular progress. It's a good idea to also schedule your study time in advance and try as best as you can to stick to that schedule.
Learning new material can be challenging, so we've compiled a few study strategies to help you succeed:
- Take notes on the various terms, practices, and theories that you come across. This can help you put each concept into context, and will create a refresher that you can use as you study later on.
- As you work through the materials, take some time to test yourself on what you remember and how well you understand the concepts. Reflecting on what you've learned is important for your long-term memory, and will make you more likely to retain information over time.
- Although you may work through this course completely independently, you may find it helpful to connect with other Saylor students through the discussion forums. You may access the discussion forums at https://discourse.saylor.org.
This course is delivered entirely online. You will be required to have access to a computer or web-capable mobile device and have consistent access to the internet to either view or download the necessary course resources and to attempt any auto-graded course assessments and the final exam.
- To access the full course including assessments and the final exam, you will need to be logged into your Saylor Academy account and enrolled in the course. If you do not already have an account, you may create one for free here. Although you can access some of the course without logging in to your account, you should log in to maximize your course experience. For example, you cannot take assessments or track your progress unless you are logged in.
- If you plan to attempt the optional Direct Credit final exam, then you will also need access to a webcam. This lets our remote proctoring service verify your identity, which is required to issue an official transcript to schools on your behalf.
